and State et New Y rlr, lieve invented cer tuin new and usefulimprovements in Sprinkler Systems, of which the following is o.specilicznion, suoli es will enable those skilled in tlie zii-tto whichit eppertziins to ineke end use the seine. f

This invention relates to what are lniown es lire sprinkler systems suche; nire usually employed in stores, factories and ptlier bnsinessplaces; and the object thereof is to pro vide on imprm'edl system of'this class in which the witter dist which the Writer posses to thesprinklers are normally'cnipty und "voter admitted'tliereto only in ceseolf lire, und when it is desired that the sprinklers should operette;and the' invention consists in the application to the mitin water supplypipe sind the Witter distribnting pipes of on apparatus whereby the liowof Wa-ter from the mein supply pipe to 4tlie writer distributing pipe orpipes is normally cut ollwbut operated in cese ol fire to admit tlie)vn-ter to the waiter dis tributing pipe or pipes und 'the sprinklersconnected dieren/ith; urther object lbeing to provide onimproved"electrical apparatus of the class specified which is simple incon@ struction und operation, :ind which will be :iutoinnticnllyopernted'to produce the desircd result in the ense of fire eshereinafter described.

The invention is lowing specification, of which the zic-coinpanyingdrawing 'forms n port, seid dreivingbeing e diagrammatic view el? unapparatus involving my invention.

In the drawing forming port of this specilicntion llieve shown et o u.moin Water supply pipe of o. Water sprinkling system oil elle classunder considerzition7 and :it l) n Wutr distributing pipewliich isconnected with the pipe o, und which is provided with sprinkling devicesc of the. usual or any preferred construction, and it will be undernstood that any desirednuniber of Water distributing pipes l) may beemployed, und also any desired number of the sprinkling de vices c.

The sprinkling devices c aire provided with fusible bends or cops" c2which ere melted in the cose of fire, end when the heat ibuting pipesthrough.

fully disclosed in the ioll reaches n predetermined degree, and thewaiter is disclierged through said sprinkling devices under the aboveconditions in the usuel manner, and the details vofthe conlstruction elthese sprinkling devices form no psrt of my invention7 and are thereforenot shown end described.,

in the operation of the apparatus Water is supposed to enter the meinsupply pipe @and poss therethrough in tl'iedirection of the nrrovv 0J,and seid pipe is provided att e predetermined point with e valve deviceol comprising` the usuel velve casing in which is nionnted e velveprovided with n stem endgtlie valve device is ol the type or providedwith en inyverdly and outwardly movable closure device, and when thestein d is rotated in one direction seid valve and stein both inove intile direction of the arroiv y, and tlie liceid Z3 with 'Wliicl'l thestem d? is provided will inove outwardly into the position indicated indotted lines.

ln the accompanying drawing .I have shown n bnttery e preferably of thegravity cell type and provided with circuit Wires f and g. Thecircuit'ivire g extends parallel ivi'tli tlie distributing pipe o sindis divided :it intervals, wlierc jllie sprinkling devices nre located,and connected therewith arelezrd Wire loops g2 which are preferablyarranged so as to inclose the sprinkling devices but Which may beerrenged in any desired manner.

I also provide n magnet it with which the circuit Wire f is connectedand another Wire e' is also connected with the magnet fr and with tneWire g, or with one of the lead wire loops g2.

The magnet is provided with an armeture y' -which is pivotedznt jz andanother wire is is connectedvivitii n binding post or Contact device la?in connection with which the nrnieture j operetes, and another Wire m isconnected with the armature y', and e spring (i3 is connected with thearmature and normally holds seid armature in the position slooivn indotted lines.

The Wire 7c constitutes one of the mein circuit Wires of the system orapparatus and nnotlicr mein circuit Wire u is elsoeinployed, and tliescmoin circuit Wires may be supplied froin any suitable source of electricsupplie The mein circuit Wire n connects with ya, switch device nlocated adjacent to the head el of the valve stem d and an electricmotor o is also employed? in the construction shown, and this motor 1sprovided with a,

Aably employ an electric gong or other signal device s which isconnected with the wire fm, by a wire t and with the wire 'n by a Wire uin which is placed a switch device u2.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawing and the followingstatement.

Under 'normal conditions the main water supply pipe a, or the part o2thereof will be filled with water up to the valve device d, but the parta3 of said pipe and the distributing. pipe or pipes b will be empty.'If, under these conditions, a fire should originate in a place providedwith my im roved apparatus and the temperature shou d rise to a point ordegree at which the heads of the sprinkling devices c will be fused ormelted, the wire loop members g2 would also be fused or melted at thesame time, and the.

circuit through the magnet h would be .broken and the other circuitcompleted through the armature and the wires c and m, the signal devices and the motor 0, and the shaft o2 of said motor would be operated.This operation of` the shaft o2 would rotate the supplemental shaft o4and the valve in the valve device al would be turned by the forked heado5 of the shaft 0*, the arms of which pass loosely through the head daof l the valve stem d2, and said valve stem and its head Z3 would bemoved outwardly into the position shown in dotted lines and the waterwould rush into the pipe a, or the part a thereof and into thedistributing pipe or pipes b and into and through the sprinkling devicesc in the usual manner.

`When the valve in the valve device d and its stem d is operated, in themanner above described, and the head cl3 of said valve stem moves intothe dotted line position, it will operate the switch n2 and the circuitthrou Yh the wires r and a and through the signal c evice s and themotor o will be broken,- but the How of water will continue until theconnecfion between the shafts o2 and o4 is broken and the valve orvalve, device (l returned to its normal position, or the flow -of waterthrough the part a2 of the (pipe a is-cut off which maybe done by han atany desired point. With my apparatus it will be seen that there will beno water in the distributing ,t pipe or pipes b nor the sprinklingdevices c,

and this as is evident will prevent the freez ing and bursting of suchpipes in extremely cold weather and thus prevent great loss and damageas will be readily understood aud,

as bgrestated, water is only admitted to Jthe"distributing pipe or pipesb and the sprinkling devices c when the valve d is opened.

i It also sometimes happens when sprin- Y kling apparatus of the classherein considered .is employed that the heads or caps'c2 of thesprinkling devices are accidentai'ly` tions thereof may be made, withinthe scope of the appended claims, without departing from the spirit ofmy invention or sacrifie-Vl -v in its advantages.
